Capacitor failure alarm in elevator inverter circuit

摘要

The present invention relates to a capacitor failure alarm apparatus for an elevator inverter circuit, and more particularly, to a capacitor fault alarm apparatus for a large capacity electrolytic apparatus which is mainly used for rectifying and smoothing an input voltage (AC voltage) to a DC voltage in a smoothing circuit portion of an inverter circuit inside an elevator control board The present invention relates to an apparatus for notifying a failure of a capacitor, a product failure, a replacement time, and the like, and is usefully used for maintenance and inspection of an elevator.
